Hhhmmm...
I'm sure you'll get a good grade from your history teacher, you did put some effort into it; maybe more than most of your classmates, BUT... The animation leaves much to be desired in the sense that the mouths are moving all the time, a looping mouth doesn't quite cut it here. The bobbing up & down of the bodies: why? Are they at sea? Are they on a pogo stick? I'll have to admit though, that I actually laughed out loud when the army attacked, that was good. The art was reasonably well drawn too. The audio needs work, it was a bit low & there was a lot of popping (too close to the mic); next time try using a windscreen on your mic, or turn you levels up a bit & turn your mic sideways (trust me) and talk across the mic, this will help to eliminate that popping; it will also allow you to get much closer to the mic, a usefull effect sometimes. Overall I have to give you credit for this, and I hope you get a high score for this from your teacher. Good luck!
